لَا فِيهَا غَوْلٌ وَلَا هُمْ عَنْهَا يُنزَفُونَ
Compare 37:47 and 56:19
highlighted words differ between verses
لَّا يُصَدَّعُونَ عَنْهَا وَلَا يُنزِفُونَ
Both describe the wine of Paradise as harmless but 37:47 uses 'la yunzafun' (they will not be drained/intoxicated) while 56:19 uses 'la yunzifun' — a root vowel shift changing the verb pattern.
